Model reference · open weights
LTX-2.5 is an open-weight video model from Abiray, listed in the AxForge catalogue. AxForge can bring it up on EU-owned hardware for you on request — with the licence handled where one is required.
About
LTX-2.5 Distilled GGUF This repository provides quantized GGUF formats of the distilled transformer from Lightricks/LTX-2.5. These weights are highly optimized for local execution, allowing you to run high-fidelity video and audio generation workflows on hardware with memory constraints while retaining the core visual fidelity of the original base model. Available Quantizations Required Supporting Components (Text Encoders & VAEs) LTX-2.5 operates on a split-component architecture. To run these GGUF diffusion models in environments like ComfyUI or local Python pipelines, you must also fetch the official Text Encoders and VAEs directly from the upstream Lightricks/LTX-2.5 repository. Text Encoders Download these from the textencoders directory: gemma4-12b-with-proj-ltx-2.5-bf16.safetensors (26.3 GB) — The full unquantized Gemma 4 12B text encoder. gemma4-12b-with-proj-ltx-2.5-comfy-int8-convrot.safetensors (15.4 GB) — An optimized INT8 text encoder specifically designed for lower VRAM usage in ComfyUI. VAEs (Video & Audio) Download these from the vae directory: ltx-2.5-video-vae-bf16.safetensors (1.47 GB) — The primary DiffVAE for highest-quality video decoding. ltx-2.5-video-vae-conv-bf16.safetensors (1.45 GB) — Convolutional video VAE for faster, lighter processing. ltx-2.5-audio-vae-bf16.safetensors (365 MB) — Audio VAE and vocoder required for synchronized audio generation. 📈 Latent Upscalers (Recommended) To achieve maximum visual fidelity and smoothness, it is highly recommended to use the official Stage 2 latent upscalers alongside this GGUF model. You can download them from the official Lightricks LTX-2.5 Repository here. Available Upscaler Models ltx-2.5-latent-spatial-upscaler-x2-bf16-1.0.safetensors (996 MB) Function: Doubles the pixel resolution of your generated video for sharp, 4K-like crispness. ltx-2.5-latent-temporal-upscaler-x2-bf16-1.0.safetensors (262 MB) Function: Doubles the framerate (e.g., 24fps to 48fps) by interpolating frames, resulting in buttery-smooth motion. ComfyUI T2V and I2V GGUF Workflows To make running this GGUF model as plug-and-play as possible, I have included two pre-configured ComfyUI workflows in this repository. You can

Using it via the API
Once AxForge deploys abiray-ltx-2-5 for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (abiray-ltx-2-5 below is illustrative; you get the exact model name on deployment.)
$ curl -sS https://api.axforge.ai/v1/videos/generations \
-H "Authorization: Bearer $AXFORGE_API_KEY" \
-H "Content-Type: application/json" \
-d '{"model":"abiray-ltx-2-5","prompt":"a drone shot over a forest"}'

Licence
The weights are open but its licence needs a commercial agreement for business use. AxForge can arrange that licence and host the model for you — you pay AxForge, we settle with the model’s maker. Ask us for a quote. Read the licence ↗
